APPENDIX
1. A brake drum comprising:
(a) a tubular inner member having an exterior surface and an interior surface suitable for
directly slidingly contacting a brake pad, the inner member being formed of a first material;
(b) a length of wire snugly wrapped in multiple turns around a portion of the exterior
surface, the wire being formed of a second material;
(c) at least one fastener for securing at least a portion of a wheel assembly to the brake
drum,
wherein the first material has a density less than that of the second material, and the
second material has a strength greater than the first material.
12. A brake drum comprising:
(a) a tubular inner member having an exterior surface and an interior surface suitable for
directly slidingly contacting a brake pad, the inner member being formed of a first material;
(b) a length of wire tightly wrapped in multiple turns around substantially the entire
exterior surface of the inner member, the wire being formed of a second material; and
(c) a tubular outer shell molded over and substantially covering the length of wire, the
outer shell being formed of a third material,
wherein the first material and the third material have respective densities less than that of
the second material and the second material has a strength greater than the first material.
17. A method for manufacturing a brake drum comprising the steps of:
(a) manufacturing a tubular inner member having an exterior surface and an interior
surface suitable for directly slidingly contacting a brake pad, the inner member being formed of a
first material having a density of not more than 0.15 pounds per cubic inch;
